Description: ------------ After upgrade PHP to 4.4 I got the following errors: Only variable references should be returned by reference in /usr/local/lib/php/DB/NestedSet/DB.php on line 52 Only variable references should be returned by reference in /usr/local/lib/php/DB/NestedSet/TreeMenu.php on line 77 Only variable references should be returned by reference in /usr/local/lib/php/DB/NestedSet/Output.php on line 109 I'm using the 1.3.6 version of NestedSet

I was able to "Fix" this "Bug" in output.php but I can'T find the other lines. Seems as if we are on different versions. Please provide the offending lines in your version of DB_NestedSet. Sorry for the delay and thanks for your help! -- Daniel Khan

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
